Chassis: WTCE 99-04The fourth Laguna built in 1999, this was also the very last produced by Williams. It was allocated to Jean Christophe Bouillon for the second half of the season. He debuted the car at Croft where he placed 11th in the first heat and then failed to finish the second. The best result for the newly signed Frenchman with this car came at Knockhill where he finished fourth and fifth. Retained by Williams, it was eventually offered for sale with a sister car in the 2005 Bonhams auction of the Williams Reserve Collection. As the entire collection was acquired ahead of the sale by a single collector, it never actually crossed the block. Later sold on, it was recommissioned for the Serbian Touring Car Championship where it raced in 2008 and 2009. It has since been restored to its original configuration by the most recent owner for use in the HSCC Super Touring Championship.
